Aldous Huxley is known as the prophet of modern philosophical thought. In his book ironically titled ‘Moksha” he quotes Vedanta तत् त्वम् असि and writes about the mystical experience thus :
Every fully developed religion exists simultaneously on several different levels. It exists as a set of abstract concepts about the world and its governance. It exists as a set of rites and sacraments, as a traditional method for manipulating the symbols, by means of which beliefs about the cosmic order are expressed. It exists as the feelings of love, fear and devotion evoked by this manipulation of symbols.
And finally it exists as a special kind of feeling or intuition — a sense of the oneness of all things in their divine principle, a realization (to use the language of Hindu theology) that “thou art That,” a mystical experience of what seems self-evidently to be union with God.
The ordinary waking consciousness is a very useful and, on most occasions, an indispensable state of mind; but it is by no means the only form of consciousness, nor in all circumstances the best. Insofar as he transcends his ordinary self and his ordinary mode of awareness, the mystic is able to enlarge his vision, to look more deeply into the unfathomable miracle of existence.
The mystical experience is doubly valuable; it is valuable because it gives the experiencer a better understanding of himself and the world and because it may help him to lead a less self-centered and more creative life.
